The scrap is discharged into troughs 9, and

,the patterntand inexact register therewith because the `die roll which cuts it 1s 1n synchromsm with the machine.

As the material travels through the roll jcalender, the web of paper is forced into the4 linoleum, embossing it. As it leaves the roll calender the paper web is wound on a roll tion table 18.

If it is desired to insert a special inset kiigure 4into .the linoleum, this may be done on an this embossing is preserved by the mask 20 i inspection table 19, lying between the rotary machine proper and the calender l2, by an operator who pulls a pattern element from the uncompressed material through an opening in the paper web and drops a special pattern element in its place. A representative special pattern element is shown in Figure 6.r Figure 7 is a corresponding mask therefor;

If desired,the special pattern element may be precompressed kwith the mask, as shown in igure 8, wherein the mask is represented by the reference character 20. The special figure isy thus-preliminarily embossed, and

as the material travels through ythe roll calender. The mask of Figure 7 is preferablyv made of a soft metal which assumes the curvature imparted to it by the roll calender 12 and thus it is cocked upwardly from the material as it leaves the calender, as indicated at 21, making the removal of such mask easy.

If it is desired merely to emboss ythe face of certain pattern elements and not to set' special designs or figures ino the goods, this may be accomplished by laying small masks onthe desired squares of the pattern through 4 the spaces in the lace-like paper web.

In Figure livthere is shown a modified form of the invention wherein corresponding partsy n Alaid linoleum, the steps consistlng in forming have been given the same reference ycharacters in Figure 3 but with an a suflixed thereto. In this form of the invention, the die roll 13a, instead of being arranged on the periph-V This paper lies overV driven in synchronism with the drum through suitable gearing, not shown. This arrangementleaves a clear space over the inspection table 19a, where the workmen may get at the goods Vwithout being hampered by the lacelike embossing web.

. f Figure 5 shows the invention applied to the manufacture, of molded inlaid material. The molded inlaid machine consistsof a bed 50 having pin bands 51 extending therearound, whereby the backing B is fed along in a step-by-step manner under stencils 52. Granulated color is strickled through the stencils onto'the backing, and when the patf tern iscompleted, this granulated lmaterial is consolidated kunder a press 53. The press 53 has a head 54 which moves down on the goods.

In yorder to prevent sticking, oiledv paper is Y fed from a roll 55 under the face of the press and is reeled on the other side at 56. The'A` lace-like web of masking paper is fed from a roll 57 and lies between the protecting sheet vof oiled paper and the linoleum mix, whereby upon lowering' of the press, this lace-like we is forced into the material and embosses it. As the goods is moved forward, the paper backing and the embossing web are also advancedv so as to 'keep them in registry with,

the material.

If special figures are to be inserted, the stencils 52 may be so formed as to leave blank spaces on' the backing ,B into which preformed pattern elements, such as those of Figure 6, may be placed either by an oper-- ator alongside the machineor the inspector along the platform 58. If desired, these in-y `naril embossed, according to t-he disclosure of Flgure 8, themask being left in place to preserve the embossing during the compresssuch texture -will be imparted to the linoleum, y

thusgiving a new and'desirableeect.

I have illustrated and described the present preferredembodiment of the invention and certain modifications thereof. yIt will be understood, however, that it is not limited to the forms shown but ma be otherwise embodied or practiced within the scope of Vthe following claims. 1

U

7. In the method Vof makingembossed inlaid. linoleum ina rotary machine effective for cutting webs of material into pattern elements and scrap and laying the pattern elements Von afbacking, the steps consisting in thus laying a major portion at least of a desired pattern, cutting a sheet of masking ma'- terial in synchronism withthe `laying of the pattern elements and placing the same' over A the pattern, and compressing the material.
